Clouds rising from aerosols

MOSCOW, November 13 — RIA Novosti. Elevated levels of aerosols in the upper atmosphere, not only increases the number of clouds, but it makes them grow up, "plump", and also increases the amount of precipitation in the rainy parts of the world and deprived of moisture over dry areas of the planet, climate scientists write in a paper published in the journal Nature Geoscience.

A team led by Lee Chzhantsina (Zhanqing Li) from the University of Maryland (USA) analyzed the results of a cycle of long-term observations of the atmosphere (ARM), which was conducted by the Ministry of Energy of

How much can you pump up the atmosphere with carbon dioxide?

Warming in particular lead to the fact that the London City Hall is surrounded by marshes because of the constant spills Thames. (Image PeppermintJ.)

There are international agreements, which need to be taken to ensure that greenhouse gas emissions are not the Earth warmed by more than two degrees above pre-industrial levels. Now, two studies published in recent years suggest that the timing of the measures are already almost out. Those who do not want the global temperature has increased by more than 2? C, must begin to actively reduce emissions without waiting for the end of the

Scientists: Russia will not receive bonuses from warming

MOSCOW, November 7 — RIA Novosti. Calculations of global warming in the 21st century on the East European Plain and West Siberia suggest that climate change will have no positive environmental and economic impacts of these regions, said the head of the Department of Meteorology and Climatology, Faculty of Geography Moscow State University Alexander Kislov, speaking at an international conference "Problems of adaptation to climate change."

Kislov, Dean of the Faculty of Geography Moscow State University Nikolai Kasimov and their colleagues analyzed using a model CMIP3 geographical, environmental and economic impacts of global warming on the East European Plain

In Texas, United States. Water is at a premium

Growing world population and climate change, depleting natural resources, and in the XXI century is facing increasingly acute shortage of water. If the year 2050 in the world, is expected to be 9 billion people, to feed them, you will need a lot of water — and yet in some regions are already enough. For example, in Texas this year due to the unprecedented drought farmers had to save every drop.

In the sky above the Texan High Plains again cloudless. The hottest and driest summers in state history adversely affected the crops. Farmer Harold Grell sighed cleanses dry

In the mountains of south-western Chinas glaciers are melting

Climate change is having a devastating impact on the glaciers in the mountains of Southwest China, writes derstandard.at.

Researchers from the Chinese Academy of Sciences in Beijing recorded "high fever" and "dramatic retreat of glaciers." The study was published Tuesday in Environmental Research Letters of the British Institute of Physics (IOP) in London.

Pentsyuy glaciers in the Himalayas, an area of 131 square kilometers, in the period from 1970 to 2001 is completely melted. Level glaciers in the mountains Yalkun Ganzhigabu dropped between 1980 and 2001, more than 1,500 meters. The researchers also identified a significant increase in the glacial

The causes and consequences of climate change

Today many pursues obsession that they are also more hot than cold. It is self-suggestion, of course. More precisely, the suggestion from the outside. "Greenhouse effect — people say, wiping the sweat from his forehead. — Climate change. Antarctic ice melt. We have to live away from the sea, until it swallowed a large piece of coastal waters. True, it is not clear — where to hide from the ozone hole? .. "But if a person is hot, it is not from global warming. And if the radio report that this year set a record temperature for a certain number

At Princeton, built a model of the Earth and the asteroid collision

A team of scientists from Princeton University (USA), led by Matthias Meschede decided to figure out how to take place seismic processes in the event of a large meteorite on Earth. To do this, they constructed a model of the collision of the planet with a giant meteor that 65 million years ago led to the formation of the Mexican crater Chicxulub.

Name Chicxulub (Chicxulub) in Maya means "demon ticks" and points to the prevalence in the area of insect pests. It is assumed that the crater diameter of 180 kilometers, is located on the Yucatan Peninsula, formed in the

British scientists plan to catch carbon dioxide giant fly swatter

MOSCOW, Oct. 27 — RIA Novosti. Scientists from the British Society of Mechanical Engineers (IME) is calculated by 2018 to develop technology absorption of carbon dioxide (CO2) emissions responsible for global warming, by setting, similar to a giant fly swatter, Reuters reported.

Mankind is trying to reduce its impact on climate change, including reducing greenhouse gas emissions, of which the largest contribution to the warming belongs to carbon dioxide. On the other hand, researchers are working on methods of "withdrawal" of CO2 from the air, but still significant progress in establishing a cheap and efficient technology could not be reached.

The ozone hole over the Arctic has captured part of Russia

As reported in the scientific journal Nature, Dr. Michel Santi (Dr Michelle Santee) and his colleagues at NASA's (Nasa's Jet Propulsion laboratory), the thickness of the ozone layer in the Arctic has reached record lows. At altitudes of about 20 kilometers, it decreased by as much as 80 percent. In essence, a "ozone hole" in the place where previously there was none.

"Ozone hole" over Antarctica usually appears — in the Southern Hemisphere. In the North — this phenomenon has always looked so small that it did not pay attention. But now thinning was just weird. And there was a

UN concerned at the increase of the world population — projected 15 billion by 2100

The world's population by the end of this century will more than double compared to 2011 and reach 15 billion people, according to a UN report, which is much more possible previous estimates of population growth, wrote Sunday The Guardian.

Previously, experts, based on the rate of growth, said that by 2100 the population will be about 10 billion. Now the world's population approaching 7 billion.

"Our planet is approaching storm that will be caused by population growth, climate change and a lack of oil. Actually, the planet does not break down and seven billion people," — told the expert
